Ring & Pinion Gear Set (R&P only) - 3.91 or 4.10 - E46 M3, E60 M5, E63 M6
(more info) Hands down - one of the best performance upgrades you can make to an E46 M3, E60 M5 or E63/E64 M6! With almost no downside you can make your BMW much quicker by swapping in a new ring & pinion gear set. The R&P acts as a torque multiplier, getting you into the power band quicker in each gear. There is an 8% increase in torque at the wheels with the shorter R&P. Want to make your car faster off the line or out of corners? This is what you need. **Note - the 4.10 is the "new" version from BMW motorsport - it is shot peened and hardend by the manufacturer for increased strength.
This item is the genuine BMW part and the ring & pinion set only. You will need to have this professionally installed into your existing differential. We also offer built differentials and exchanges, click
